In vitro evaluation reveals glutathione's effects on apoptosis and DNA damage in kidney cells under high glucose conditions, suggesting its protective role.
This study was planned to investigate the effects of glutathione, known to be a strong antioxidant, on caspase-dependent apoptosis and oxidative DNA damage in the kidney cells (BHK-21) exposed to high glucose. BHK-21 cell line was cultivated by regular passages in vitro conditions. Study groups were set up as control, study and its combinations groups ((Glucose; (285 mM, HG), glutathione (250 µM)). After 24 hours of incubation, trypsinized cells were disrupted by freeze-thaw method and analyte was prepared. Caspase 3, 8, 9, M30 and 8-OHdG (oxidative DNA damage marker) levels were determined using commercial ELISA kits. M30, caspase 3, 8 and 9 which are the parameters of apoptosis, were found highest in the HG group. In GSH-treated groups, these parameters decreased slightly. There was no significant difference in the levels of 8-OHdG which is the indicator of oxidative DNA damage.
